Developmental control of plant Rho GTPase nano-organization by the lipid phosphatidylserine

Added: 19.05.2019 17:39 | 0 views | 0 comments

Rho guanosine triphosphatases (GTPases) are master regulators of cell signaling, but how they are regulated depending on the cellular context is unclear. We found that the phospholipid phosphatidylserine acts as a developmentally controlled lipid rheostat that tunes Rho GTPase signaling in Arabidopsis. Live superresolution single-molecule imaging revealed that the protein Rho of Plants 6 (ROP6) is stabilized by phosphatidylserine into plasma membrane nanodomains, which are required for auxin signaling. Our experiments also revealed that the plasma membrane phosphatidylserine content varies during plant root development and that the level of phosphatidylserine modulates the quantity of ROP6 nanoclusters induced by auxin and hence downstream signaling, including regulation of endocytosis and gravitropism. Our work shows that variations in phosphatidylserine levels are a physiological process that may be leveraged to regulate small GTPase signaling during development.

Fact-Checkers Give Stacey Abrams a Pass on Victory Claim

Ever since she narrowly lost the Georgia governor's race six months ago, Stacey Abrams has been claiming that she "won" the election. Most recently, on April 28 she told The New York Times Magazine, "I cannot say that everybody who tried to cast a ballot would've voted for me, but if you look at the totality of the information, it is sufficient to demonstrate that so many people were disenfranchised and disengaged by the very act of the person who won the election that I feel comfortable now saying, ‘I won.'"
